Key Facts

  • 2% of the UK’s net gas imports
  • 69% of CHP uses natural gas
  • 89% of CHP is in industry 
  • 6% of the UK's power needs are met through CHP 
  • CHP saves 15 million tonnes CO2 a year.


Gas meets 70% of the UK's heating needs

How we calculated the CHP gas savings 

CHP used 71,143 GWh of natural gas in 2012 to generate:

33,153 GWh of heat
17,907 GWh of electricity

If this heat and electricity was generated separately, would need 79,030 GWh of natural gas

Assume 81% boiler and 47% gas power efficiency

CHP saved 7,887 GWh of natural gas in 2012 equal to 0.706 billion cubic metres

How we calculated shale gas production 

A shale gas well is expected to produce 3 billion cubic feet of gas per well over 20 years

3 billion cubic feet equal to 0.0850 billion cubic metres

CHP reduces gas imports: The gas saved through the use of CHP is equal to: 

£165m benefit to UK balance of payments
Assumes import price of £21/MWh.

477,000 homes’ annual gas demand

Assumes annual demand of 16,500 kWh

CHP uses up to 30% less gas than traditional generation. Source: The Future of Heating: Meeting the Challenge
